Serena said: “I would really like to take this moment to congratulate Venus, she is an amazing person. There is no way I would be at 23 without her. There is no way I would be at one without her.

"She is my inspiration, she is the only reason I am standing here today and the only reason that the Williams sisters exist.

"Thank you Venus for inspiring me to be the best player that I could be and inspire me to work hard every time you won this week I felt like I got a win too.”

"I have been right there with you, some of them I lost right there against you. Yes, that is weird but it is true. But it has been an awesome thing much your win has always been my win, I think that you know that.

"Those time that I couldn't be there, didn't get there, you were there. I am enormously proud of you, you mean the world to me. God willing, I would love to come back.”

The nervous start to the match started with four consecutive breaks of four.

In the third game, Serena received a code violation for smashing a racquet in frustration when a net cord fell her sister's way.
